I need serious help guys, here’s the rundown. I just removed my old intercooler pipes and replaced with injen intercooler pipes and welded a flange on and mounted an atmospheric blow off valve and hooked into vacuum lines. Then I unbolted diverter valve and zip tied it out of the way leaving it plugged in and installed a block off plate. And now I keep popping a check engine light and traction control light and I have shitty boost and around 3500 rpm Itll go into limp mode. I don’t know what to do. Do I need a tune? Someone said to just bolt the diverter valve back up and I did that and for about 15 seconds the car was fine and incredibly quick and then went into limp mode and after that shitty boost again.. any ideas?
